Conditions

Outcome Measures

Primary Outcomes (4)

  • Myocardial 68Ga-FAPI (68Ga-Fibroblast Activation Protein Inhibitor) volume

    Myocardial 68Ga-FAPI volume will be determined by a PET (positron emission tomography) scan and measured in cm3

    Baseline and 6 Months

  • Mean Standardized Uptake Value (SUVmean) and Max Standardized Uptake Value (SUVmax)

    SUVmean and SUVmax will be determined by a PET (positron emission tomography) scan and measured as a dimensionless ratio

    Baseline and 6 Months

  • Area of 68Ga-FAPI (68Ga-Fibroblast Activation Protein Inhibitor) uptake

    Area of 68Ga-FAPI will be determined by a PET (positron emission tomography) scan and measured as a % of polar map.

    Baseline and 6 Months

  • 68Ga-FAPI target-to-background ratio

    68Ga-FAPI target-to-background ratio will be determined by a PET (positron emission tomography) scan and measured as a dimensionless ratio.

    Baseline and 6 Months

Study Arms (3)

Obese subjects with HFpEF (heart failure with preserved ejection fraction)

EXPERIMENTAL
Drug: 68Ga-FAPI (gallium-68-labeled fibroblast activation protein inhibitor)

Healthy subjects

ACTIVE COMPARATOR
Drug: 68Ga-FAPI (gallium-68-labeled fibroblast activation protein inhibitor)

Interventions

68Ga-FAPI is a gallium-68 fibroblast activation protein inhibitor that will be injected into subjects during a PET (positron emission tomography) scan

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients aged ≥ 30 years old with exertional dyspnea (NYHA II and III) and LVEF ≥50%
  • BMI ≥ 30
  • New diagnosis of HFpEF based on RHC at baseline (elevated PCWP at rest and/or during exercise)

You may not qualify if:

  • Primary cardiomyopathy or pericardial disease or ≥ moderate valvular disease
  • Dyspnea due to lung disease or CAD
  • Severe anemia, liver, or renal disease
  • Active cancer
  • Systemic active inflammatory or autoimmune disease (e.g. rheumatoid arthritis, SLE, etc.)
  • Recent hospitalization (\< 30 days) or coronary revascularization (\< 90 days)
  • Patients already taking SGLT2i and/or GLP-1A
  • Pregnant or breastfeeding
  • Inability to tolerate supine position for the PET/CT or CMR scans.
  • Contraindications for safe CMR scanning (e.g., uncontrolled claustrophobia, cochlear implant, implanted neural stimulator)
  • Known gadolinium allergy
  • Presence of implantable cardiac pacemaker or defibrillator or mechanical valve.
  • Ambulatory patients aged ≥ 18 years old
  • New referrals to the Sarcoid Clinic with a confirmed but untreated diagnosis of definite or probable CS based on 2014 HRS consensus (see Table 2)
  • With a positive cardiac 18F-FDG PET scan within 30 days.
  • +17 more criteria
